(Noun) From the band Gwar mythos, the lead singer and alien from the planet Scumdogia Oderus Urungus' sexual reproductive organ. It resembles a human male penis and spurts blood when excited. Looks slightly like a huge slug with huge saggy testicles dangling from the base.

Oderus had his cuttlefish of cthulhu confiscated in South Carolina by the cops.
